UNITED STATES GORNELIS VAN DER LEUN, OF THE HAGUE, NETHERLANDSV I LooK.

Specification of Letters Patent.

a li ation filed March e, 1919. Serial No. 280,994.

Be it known that I, CoRNnLIs VAN DER LEUN, private man, a subject of the Queen of the Netherlands, residing at The Hague,

the Netherlands, 45 Columbusstraat, have invented certain new and useful Improvements in Locks, of which the following is a specification. 1

This invention relates to looks and has for its object the provision of a simple, in-

expensive, and reliable safety device which is quickly and easily manipulated by one who knows the combination, but which can? not be manipulated by an unauthorlzed person.

In general, the invention comprises looking means in the nature 'of one or more balls, rolls, cylinders, or the like, sh1ftablefrom one to the other of two compartments Flg. 2 1s a similar vlew showing the locking means'in' posltlon to "secure said two 4 respectively, connected by a'suitable pasor pockets so as to prevent'or allow relative movement of two members,the movement of said locking means from one'to' the other of said pockets being controlled by a number of superimposed relatively shiftable plates. An illustrative embodiment of the invention' is shown in the accompanying drawings, in which- Figure 1 isa transverse sect1ona l deta1l showing the locking 'means in posltion to permit the" relative movement of the two parts against relative movement Fig; 3 is aside view," partly SGCtlOIltl, of the same. Y

Fig. 4 is a side tional, of the same.

In the aforesaid 'figures -the devlce 1s shown'as particularly applicable to a bicycle hub. However, it will be understoodthat this is merely illustrative of the'invention and that it is equally suitable for use on other devices and for other purposes.

The construction as illustrated comprises a pair of relatively movable members or parts 7 and 8 provided with pockets 11 and sage and between which the'ball 2 is movable either for securing the two members" 7 r Although but one spec fic embodlment of v against-relative rotation, or releasing them 7 so as to'perniit said relative rotation.

In the specific embodiment, the'part 8 is when the two parts elevation, also partly sec- I in the nature of anaxle, and the'part 7 a 'hub' rotatably supported on said axle. The axle 8 1s provided with an enlargement 10 in which two pockets 11 are formed for the purpose of providing a seat for the ball 2 are to besecured against relative rotation.

The hub 7 has an axially disposed offset part 1n which the pocket .4 is formedand between which and'the enlargement '10 the Y plates 5 are slidablymounted. The plates 5 areherein shown to be three in number,

an aperture near one end thereof so arranged that it is adaptedto be moved into tworupper Plates are halfas wide as Patented June 1, 1,920..

the under one of which is provided with the lower plate and are slidablymounted upon s'aid lower plate in the same plane with each other. Said upper plates are each provided with a semi-circular recess in'the abutting edges, 'which recesses are normally 111 staggered relation.

These two upper plates are independently shiftable so as to bring the semi-circular recesses into regis-' tration'with each other and with the aperture in thelowermost plate and the passage connecting the pockets 4 and 11. Suitable gra'duations'are formed "on thetendsof the plates" 5,, which serve asa 'guide in properly "setting the plates to .connectthe pockets 4 a'ndll for permittingtheeball 2- to pass from one to the other.; i I

A coiled spring 12' is' concentrically 'arranged in the pocket-4-so as to'bear upon the uppermost plates '5 and hold them firmly against the lowermost plate and the lower most plate against themeinber 7, thepressure of the spring exceedingthe weight of the ball 2 so as tore'nder it impossible for one to find. out 'how 'to adjust the plates merely by feelingthe weightof the'ball.

' The member 7 has a recess formed in the inner periphery thereof atone side of the passage connecting the two pockets 4 and 11 as'is clearly shown inrFigs. 1 and 2. This this invention has been' herein shown'and described, it will be understood that some it is in 55 of. saidapockets to the other.
